Dr. Mercola's Joint Formula contains a unique patented, fast-acting ingredient that goes beyond glucosamine and chondroitin to help reduce cartilage breakdown and provide the building blocks for healthy joint function and connective tissues.* A small, single daily dose provides three-way, fast-acting support against temporary, exercise-induced pain, stiffness and cartilage breakdown.*

They've also added three additional joint health-supporting ingredients to help prevent and slow down free radical damage to joints and to help reduce friction in your points, allowing you to move more easily.*
